A broadcast capable file system is disclosed. In a method, a server may receive a file request from a requesting client and prepare a broadcast response to the file request. The broadcast response may be directed to a group of clients of which the requesting client is a member. In another method, at least one of the clients of the group of clients may submit a file request to the server. Each of the clients of the group may receive a broadcast response to the file request. The broadcast capable file system may be implemented between a server computing device and multiple client computing devices. The server computing device and multiple client computing devices may be included in a network testing system.

Broadcast capable file system

There are disclosed processes and systems relating to optimized network traffic generation and reception. Application programs and a protocol stack may share a memory space. The protocol stack may designate available bandwidth for use by an application program. The application programs may store descriptors from which the protocol stack may form payload data for data units.

Protocol stack using shared memory

A virtual interface is disclosed. A method may include allowing upper layer software to transparently access the capabilities of a network device via a virtual interface as if the network device were in a computing device in which the upper layer software is resident. A communication channel may be established with a computing device. A virtual interface to a network device in the computing device is created. Incoming data units directed to the network device are received via the communication channel, and are made available via the virtual interface. Outgoing data units directed to the virtual interface may be forwarded to the network device via the communication channel. The methods may be implemented on computing devices that include network cards, including computers and/or network testing systems.
